But I don't found mirror-0(raid1) in zfs.

If you add a disk instead of attaching it, you changed from a mirror (RAID1) to a stripe (RAID0). Therefore, you no longer have redundancy and your data is at risk!

Ah i understand.

So i want to change a stripe to a mirror.

Please suggest for that.

Thank you.

Remove the second vdev disk, which is possible since very recent ZFS version. Then attach it as a mirror correctly.
